We are buying an operating business. Can we deduct diligence costs and a closing-contingent banker fee?
Do not deduct the entire deal-fee ledger—or capitalize every invoice—just because the acquisition closed. Federal rules generally require capitalization of amounts that facilitate an acquisition of an operating business. In a covered transaction, ordinary investigatory work before the regulation's bright-line date can receive different treatment from post-letter-of-intent diligence; certain inherently facilitative work must be capitalized regardless of timing. A closing-contingent banker fee is presumed facilitative unless adequately documented otherwise, but a qualifying buyer may elect a 70% nonfacilitative/30% capitalized allocation under Revenue Procedure 2011-29. “Nonfacilitative” is not an automatic current-year deduction: the taxpayer and applicable deduction rules still matter.
A founder or CFO acquiring a substantial operating company should resolve this before the acquisition-year return and purchase-price allocation are locked. AE can review invoice-level work, engagement letters, deal dates and entity structure with the transaction team.
First identify the buyer, the transaction and the work
The final Treasury and IRS regulations under section 1.263(a)-5 cover, among other things, acquisition of assets constituting a trade or business and certain acquisitions of ownership interests. Who contracted for and paid each adviser matters. An invoice paid by the target, an acquisition vehicle, a shareholder or a lender is not automatically a buyer deduction merely because one closing statement nets the amounts together. Reconcile reimbursed and indirect payments as well as the deal funds flow.
Classify the service, not the provider's title. A single law-firm or accounting invoice may include early target screening, tax due diligence, drafting the purchase agreement, financing, and post-close integration. The regulation treats many transaction-closing activities as inherently facilitative, including securing a formal written appraisal or fairness opinion, structuring the transaction, preparing and reviewing transaction documents, obtaining regulatory approvals, and conveying property. Integration work is expressly distinguished from facilitating the acquisition; borrowing costs have their own treatment. A lender fee should not simply be put into acquired-business basis.
The letter-of-intent date changes ordinary diligence analysis
For the regulations' covered acquisitions, a non-inherently-facilitative amount generally facilitates the transaction only to the extent it relates to activities performed on or after the earlier of two dates: a letter of intent, exclusivity agreement or similar written communication executed by buyer and target, or the relevant governing-body authorization of material terms. When governing-body approval is not required, the regulation supplies a binding-contract rule for that prong. A confidentiality agreement alone is not treated as the similar written communication. Preserve actual signed dates and time records; the invoice date or closing date does not establish when the service occurred. The bright-line rule does not convert every earlier bill into an immediate deduction; the business's status, section 162, start-up rules and other provisions still need review.
Formal valuation, deal structuring and contract drafting do not become deductible merely because a banker or lawyer did them before the letter of intent. Conversely, a general financial or tax diligence review should not be classified as inherently facilitative just because the deal later closed. The IRS regulations deliberately distinguish general diligence from formal appraisal or fairness-opinion work. AE's asset purchase-price allocation guide addresses what the buyer bought; this guide addresses what the buyer paid advisers to pursue the acquisition.
Closing-contingent banker fees need their own election decision
Under section 1.263(a)-5(f), a fee contingent on successful closing is presumed to facilitate the transaction except to the extent contemporaneous documentation establishes a nonfacilitative portion. Revenue Procedure 2011-29 offers a separate safe harbor for a taxpayer paying or incurring such a fee in a transaction covered by section 1.263(a)-5(e)(3). If elected, the IRS will not challenge treating 70% as nonfacilitative and capitalizing 30%. The election requires a statement attached to the taxpayer's original federal return for the year the fee is paid or incurred, identifying the transaction and the deducted and capitalized amounts. It applies to all of that taxpayer's success-based fees in that transaction and is irrevocable. It is not a universal “deduct 70% of all banker fees” rule; noncontingent retainers, different transactions and other tax provisions require separate analysis.
For a taxable acquisition, the buyer's capitalized facilitative costs generally increase basis in acquired assets or stock, depending on the legal deal. That can affect depreciation, amortization or later disposition rather than creating an immediate deduction. Coordinate the cost schedule with the signed deal form and stock-versus-asset analysis; book-accounting expense labels do not settle the federal tax return.
A worked invoice example before the acquisition-year return
Assume an operating-company buyer pays $120,000 for general due diligence before any relevant bright-line event, $80,000 for the same type of work after both parties sign an exclusivity letter, $40,000 to draft and negotiate the acquisition documents, and a $300,000 closing-contingent banker fee. Assume the transaction and taxpayer qualify for the Revenue Procedure 2011-29 safe harbor. Under the regulation's timing test, the $80,000 later diligence and $40,000 inherently facilitative drafting require capitalization. If the buyer timely elects the safe harbor, it treats $210,000 of the banker fee as nonfacilitative and capitalizes $90,000; thus $210,000 of these identified fees is capitalized before considering any other costs. The $120,000 early diligence and $210,000 nonfacilitative banker portion are not automatically deductible; AE would separately test whether the buyer's existing trade or business and other tax rules support a current deduction or a different treatment.
If the banker fee is instead a fixed retainer payable even if the transaction fails, do not apply the 70/30 success-based safe harbor to it just because a banker issued the invoice. If the target, rather than the buyer, is the contractual payer, do not put its cost on the buyer's return without analyzing the actual legal obligation and indirect-payment rules. This example omits state taxes, financing fees, tax-free reorganizations and a possible acquisition vehicle with no preexisting operating business; those facts can change the result.
A five-part review before filing
- Map the legal deal and payer. Identify stock versus asset acquisition, taxable versus tax-free steps, buyer and target entities, engagement-letter signers, reimbursements and funds-flow obligations.
- Build a dated service ledger. Split each invoice by task and service period. Retain the signed letter of intent, exclusivity agreement, board or member approval, binding agreement and contemporaneous adviser descriptions.
- Separate special categories. Flag formal valuations, contract drafting, regulatory approvals, financing and post-close integration; do not lump them into “due diligence.”
- Decide the banker-fee path. Test whether payment truly depends on closing and the transaction is covered. Compare documented actual allocation with the irrevocable Revenue Procedure 2011-29 election before the original return is filed.
- Reconcile returns and basis. Tie deductible, capitalized, financing-related and otherwise deferred amounts to the buyer's tax return, asset or stock basis schedules, purchase-price allocation and any Form 8594 reconciliation.
Records and failure points worth catching
Gather adviser engagement letters and amendments; detailed invoices, time entries and deliverables; transaction timeline and approvals; diligence reports; financing documents; banker compensation schedule; acquisition agreement, closing statement and reimbursements; purchase-price allocation; and filed or draft entity returns. If the books expense all deal fees, preserve the book-to-tax adjustment and basis roll-forward instead of relying on that label.
Common failures: using the invoice date as the service date; calling every adviser charge due diligence; deducting inherently facilitative drafting before the letter of intent; treating the 70% safe-harbor allocation as a guaranteed deduction; attaching no election statement to the original return; applying the safe harbor to a noncontingent fee; mixing buyer, target and shareholder invoices; and forgetting that capitalized buyer costs must be tracked in the right acquired-asset or stock basis. AE can turn the deal-room documents into a defensible return schedule before filing or review a return that already used one blanket account.
Primary authorities and related AE guidance
This is a federal decision framework, not a deduction opinion. Transaction structure, service timing, payer identity, accounting method, whether the buyer already operates a trade or business, financing, start-up rules, state law and the actual return year can change the treatment. A nonfacilitative allocation is not itself proof that a current deduction is available.
